Abstract

We exploit the critical structure on the Quot scheme QuotA3(O⊕r,n), in particular the associated symmetric obstruction theory, in order to study rank r K-theoretic Donaldson-Thomas (DT) invariants of the local Calabi-Yau 3-fold A3. We compute the associated partition function as a plethystic exponential, proving a conjecture proposed in string theory
